This is a replacement lithium-ion battery pack for Theradome LH40, LH80 and LH80 Pro laser hair-growth helmets. It is a 3.7V, 3400mAh cell (12.58Wh) built to the same dimensions as the original, using an INR18650 cell in a 1S1P configuration. Cameron Sino is a long-established third-party battery maker, so this is a like-for-like swap rather than an upgrade. It suits owners whose helmet no longer holds a charge and who want to keep using it instead of replacing the device.

This is a 3.7V, 3400mAh lithium-ion replacement battery with a rated energy of 12.58Wh. It is designed to replace the original battery in the Theradome LH40, LH80 and LH80 Pro, and is made to match the original's dimensions and fit.
The battery is made by Cameron Sino in an ISO 9001 certified factory. Its capacity may differ from the original battery, either to increase runtime or because of cell availability. It will still fit and charge as long as the device and battery number are compatible.
To confirm fitment, check your device model, the battery number printed on the original battery, and the manufacturer. A Li-ion battery lasts about 400 charge cycles, and a partial discharge and recharge still counts as a cycle. Recharging when about 10% of the charge is left helps extend battery life.
